DUPLICATING PAD OR SHEET.

SPECIFICATION forming part of Letters Patent No. 589,372, dated August31, 1897. Application filed December 23, I896. fierial No. 616,796. (Nospecimens.)

To all whom 1 may concern;

Be it known that I, HORACE P. BROWN, a citizen of the United States,residing in the city and county of San Francisco, State of, California,have invented an Improvement in- Duplicating Pads or Sheets; and Ihereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to an improvement in the duplication or manifoldingof marks or entries upon separate sheets, such as shipping-receipts,cash memoranda, pads, and sheets generally where any repetition of themark or entry is required.

It consists, essentially, of the application by printing or other meansto one surface of a sheet of a non-drying transparent ink or othersuitable material, which serves to duplicate upon a following sheetanyentry or mark made upon the face of the first-named sheet or of sheetsanterior thereto, and in certain details of construction and mounting,which will be more fully explained by reference to the accompanyingdrawing, in which the figure illustrates my invention as applied to areceipt-book.

In the method now generally employed for making duplicate or triplicatereceipts, cash or memorandum tags, Where more than one copy is desired,it is customary to employ independent sheets of carbon-paper, which arelaid between the upper and lower sheets, so that when a mark or entry ismade upon the upper sheet it Will be transferred by means of the carbonsurface of the next sheet below and this again to a third sheet by theuse of These carbonsheets are necessarily loose and changeable from onepart to another of the book, pad, or other record for the purpose ofeach new entry and are somewhat expensive to produce.

In my invention I print or apply upon the back of a sheet'by means ofany printingpress or other suitable means a surface of non-drying andtransparent ink, which when superposed over another sheet will transferany entries or marks made upon the front side of said sheet or upon anysheet anterior thereto to a subsequent sheet, which may be placed belowthe one having the above'described surface. This surface may be auniform tint or made in half-tone, so called, or

in any other suitable manner. This ink being transparent will not in anyway interfere with any printed matter which it may be desiredto'haveupon the back of the sheet, as in the case of conditions, &c., which areprinted upon shipping-receipts and other like documents.

The word ink is here employed to designate any suitable substance orpreparation trated my invention as applied to a system ofshipping-receipts which is usually employed in duplicate or triplicate.In this case the sheets A, B, and G are respectively the shipping-order,the duplicate shipping-receipt, and the original shipping-receipt. Theseare bound in series of three into a book of any suitable shape or size,the sheets A and 0 having lines of perforation along the back edge closeto the binding, so that they can be easily removed. The first sheetconsists of the shipping-order and the second the duplicateshipping-receipt. Upon the back of each of these sheets is imprinted asurface of a transparent ink, which may be made of any suitable ordesired color. In the present case I have used'an ink of such a colorand character that the conditions which are usually printed upon thebacks of such receipts can be printed in black ink thereon and caneasily be read through the transparent surface which has been appliedthereto. These first two sheets having this imprinted or preparedsurface are slightly shorter than the sheet 0, as shown, so that eachseries of three is easily separated and identified by reason of thefront edge of the sheet 0 projecting a short distance beyond the edgesof the other two.

The entry being made upon the first sheet A with pencil or other markingimplement the marks will be transferred, respectively, to sheets B andO. The first, constituting the shipping-order, may then be removed anddelivered to the shipper and the third,which is the originalshipping'receipt, is also removed in the same manner, leaving the secondor duplicate shipping-receipt in the book. The next series is used inthe same manner, and so 011 through the book.

In order to prevent the marks being transmitted beyond the desirednumber of sheets, the third sheet C will have no transferringsurfaceprinted upon it. Consequently the transfer is limited to the sheetsubsequent to the last one having this surface upon it.

For convenience in writing and to provide a properly hard surface toinsure the clear marking through the various sheets 1 cmploy a flap D,of hard pasteboard or other suitable material, which is loosely hingedto the front edge of the rearmost cover of the book, as shown at E, sothat it may be folded over the leaves of the book which are behind theones to be written on, and these latter leaves, as A, B, and C, are thenlaid down upon this surface, so that the marking or writing is readilytransferred as far as desired. This flap will also serve to prevent atransfer of the mark beyond itself if introduced behind sheets whichhave the 'transferring-surface upon them.

It will be manifest that this transfer-surface may be imprinted orprepared directly upon the sheets, either bound or unbound, which formthe shipping receipts and orders, or cash or memorandum tags or pads ofany description, or it may be imprinted or applied upon intermediatesheets which are secured in rotation with those upon which the marks areto be placed, the essential feature of the invention consisting inapplying the duplicating or manifolding surface by printing upon oneside of a sheet.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The improvement in manifolding consisting of sheets having appliedupon the printed backs thereof a surface of non-drying transparenttransferable ink.

2. The improvement in manifolding for sheets, pads, or books consistingof sheets arranged in series having applied upon the printed backsthereof a surface of non-drying transparent transferable ink and adevice for separating said sheets into groups of as many as the numberof copies desired and preventing a further imprinting upon subsequentsheets.

3. The improvement in manifolding consisting of sheets bound together inseries of as many as there are desired copies having imprinted upon theprinted backs of those sheets from which copies are to be transferred, anon-drying transferable ink, perforations or means for separating thesheets from the binding being formed upon those sheets which are to beremoved, and the final sheet of each group having its edge projectingbeyond the previous'one so as to separate the groups.

4. The improvement in manifolding-sheets bound into books consisting ofa surface of non-drying transferable and transparent ink imprinted uponthe printed backs of sheets through which the transfer is to be made,said sheets being bound in series of as many as there are copiesrequired and with the front edge of the final sheet projecting slightlybeyond the anterior ones to separate the groups, lines of perforationsformed adjacent to the binding along those sheets which are to beremoved from the book, and an impenetrable flap or surface looselyhinged to the front edge of the book and adapted to be folded betweenthe series of sheets to prevent a transfer beyond the particular seriesrequired.

In witness whereof I have hereunto set my hand.
